LOOSE-LEAF LEDGER, BOOK, AND THE LIKE.

' Application filed November 20, 1922. Serial No. 602,073.

To all whom it may concern:

Be it knownthat- We, HARRY Wenswon'rrr WRIGLEY and JAMES ALBERT RmewAboth British subjects, residing at Manchester, county of Lancaster,England, have invented certain new and useful Improvements in Loose-LeafLedgers, Books, and the like, of which the following is a specification.

This invention relates to loose leaf ledgers, loose leaf books, cardindexes or the like, of paper, card ,or other suitable material, inwhich a number of leaves'or sheets are arranged to overlap one anotherwith a margin at the lower edge of each leaf or sheet, projecting belowthe one above and left exposed and visible, upon which a name, subjeotor address, or reference figures or letter may be written, with atransparent sheath to protect the exposed margin.

The ledger or book may comprise a single unit or a number of such units,each unit being built up of a number of separate leaves or sheets whichnest one into the next.

According to the invention the leaves or sheets which go to form aseparate unit are each formed with a loop at one side (preferably theleft) to receive a retaining bar and into which the edgeof the leaf orsheet above it nests, and-when nested together a single retaining bar ispassed through the several loops of the assembled and nested leaves andsecured in position top and bottom by a suitable means, a cover beingpreferably provided to enclose and protect the nested edges of theleaves-and a sheath of transparent material may also be applied to thebottom edge of each sheet to protect it during use or handling.

The invention will be fully described with reference to the accompanyingdrawings Fig. 1 is an expanded blank of a single leaf or sheet A inpreferred form.

Fig. 2 is a view of a single leaf or sheet folded to form loop a. 7

Fig. 3 is a longitudinal section of a single leaf or sheet detached.

Fig. 4 is a view showing position of two leaves A or sheets nestedtogether and secured by retaining bar B.

Fig. 5 is a view of top or uppermost leaf or sheet A.

Fig. 6 is a section of leaf or sheet A.

Fig. 7 is a separate view of a signal F.

Fig. 8 is a side elevation of a single unit showing a number of leavesA. with covers Fig. 15 is a perspective view of the same closed.

The book, ledger or card index'may comprise a single unit or a pluralityof such units, bound together or secured in a loose back from which anyone can be removed and replaced at will.

Each unit is formed or built up of a number of leaves or sheets A,nested together and detachably secured at one edge (preferably at theleft side), one leaf overlapping the 50 next and leaving a margin aalong the lower edge exposed, upon which any name, address or referencefigure or letter may be inscribed.

Each leaf or sheet A is folded over at the lower corner of the sideretaining edge to 35 form a loop a, and is secured by an eyelet a or bya wire staple or by an adhesive or otherwise. The eyelet a also forms astop for the lower edge of the next sheet to abut against, thusleaving amargin a along the 99 lower edge of the leaf or sheet beneath uncoveredand exposed. Instead of shaping and folding over the edge of the sheetA, as shown, it may be out or shaped in any other convenient form tomake an Or a strip of paper, card or fabric may be attached to it toform the loop The sheets or leaves A to any number are assembled one ontop of the other with the folded or looped edge of one nested into thefolded edge of the preceding sheet, and so on, thus each leaf covers thepreceding one below it, with the exception of the margin a which is leftexposed.

The top leaf or sheet A is preferably of 1 card and is similarly formed,with an additional eyelet a or staple or stop to bear against the backof the retaining bar B to prevent the sheets falling forward out ofalignment at the opposite edge.

When the sheets A are assembled in pos1= tion a retaining bar B ispassed through the enclosed loop a.

loops a formed in the several sheets extending from the top to thebottom, and is secured in position by the ends being in serted inpockets affixed to a stiff strip or cover 0 or G at the back of thesheets. Thus'each sheet or leaf A is securely held 7 in place and can beturned over to expose flexibly attached to the strip or cover C or C 'tofold over and protect the retaining edges of the sheetsA, and be securedat top and bottomby hinged clips Z) or otherwise.

Over the lower exposed margin a of each sheet a transparent sheath E ofcelluloid or other suitable material may be fitted to protect the edgefrom wear when in'use, and this may also form a pocket for colouredsignals or indicators F to draw attention to the leaf or to holdan'ex'tra or additional sheet or card, and the top sheet'maybe fittedwith a similar sheath E to form a pocket to contain a number of thesignals F.

Each unit comprising the leaves A secured by the bar B and back cover orstrip 0 and front strip or cover D, may be used separatelyor may beenclosed in additional covers D" Fig. 11, or each of the units may beprovidedrwith a binding strip G and a number bound into, a hookerremovably secured thereto by pins or screws 9 passing through holes inthe binding strips. 1 'The covers D may have applied to them at H indexor reference letters or figures.

What we claim as our invention and desire to protect by Letters Patentis 1. A loose leaf unit adapted for a book, ledger, card index or thelike of thetype set forth, comprising a plurality of leaves, each leafformed with a loop along one edge, and nested into the leaf below itleaving a margin exposed along the bottom eeaozse of the latter, aretaining bar passed through the loops of the several leaves, and astill back strip or cover with means to receive and secure the ends ofthe retaining bar.

2. A loose leaf unit adapted for a book,

ledger, card index or the like of the type set forth, comprising aplurality of leaves, each leaf formed With a loop along one edge, andnested into the leaf below it leaving a margin exposed along the bottomof the latter, a retaining bar" passed through the loops of the severalleaves, and a stiff back strip or cover with means to receive and securethe ends of the retaining bar, and a stiff front strip With clipstcsecure it to the back strip.

3. A leaf or sheet adapted for use in a loose leaf book,ledger card,index or the like of the typeset'forth, folded over at leaves to securethemin position, stiff-covers,-

ineans affixed thereto to. secure the bars, a holder and'means toenclose a number of such units in the holder from which they can beremoved and replaced.
